Last minute preparations are underway for Toa Samoa and Mate Ma'a Tonga fans on Sunday night.
Despite the game being played in Sydney, New Zealand fans are far from deterred, flags have been flying off shelves in Ōtāhuhu town centre.
Bargain House store owner Garry Wang has been stocking up and staying open late.
"Over two weeks, maybe over a thousand [flags] now, I think probably about 200, or so yesterday."
He would not be drawn on what team has had more demand for merchandise.
"This is a hard question, you know, we have a lot of the Samoa and Tonga fans here I think it's equal you know."
One family 1News spoke to had travelled from Hamilton to find the right supporter gear.
The Mother of a Tongan and Samoan baby son was buying a tiny Tonga jersey and flag. "He doesn't have a choice," she said.
Others were buying Toa Samoa flags and jerseys down the road. "Decorate the car, decorate the house, decorate the kids," one excited supporter said.
For the past few weeks, fans have taken to the streets and motorways around New Zealand and further afield to show their support parading flags.
With a 10pm start time, restaurants and bars are also keeping their doors open late.
Helu Vilikikihi Tongan restaurant was planning on staying open till 2am.
"Yes, it's going to be pretty busy like when the people do the parade," said worker Leni Pousini.
Despite serving Tongan food, she said the restaurant is expecting diners from both sides.
"We have to support the Samoan we are friends we all come from the pacific islands."
It is not just pride on the line tonight the winner of the game will face the Kiwis in the semi-final.
Police are showing their support but warning fans to still obey the law after cautioning several drivers in Tauranga last night.
